I'm fine up until the last three words. Roughly: "They fought with even more hatred than force, the Romans because they were offended that the conquered took up arms unprovoked against the conquerors, the Carthaginians because they believed proudly and greedily SOMETHING SOMETHING SOMETHING."

I'm reading "imperitatum" as a perfect passive participle--but what does it modify? And "victis" is either a dative or an ablative plural--but why would the Carthaginians think anything was done to them (I suppose I'm supplying a "se") by the conquered when they were in fact the conquered?

Canon Roberts's translation is "The Carthaginians bitterly resented what they regarded as the tyrannical and rapacious conduct of Rome," which is elegant but not particularly helpful as far as grammar goes.

I'm sure it's very obvious and simple, but I'm knocking my head against a wall trying to get there. Can anybody offer a hint or two?

What Shenoute says...Ut dicit Shenoute"with [/as for] the Carthaginians, because they believed they [/it] had been governed arrogantly and selfishly [/to them] as ones conquered [/having been conquered]."
